Abstract: AERODYNAMIC SURFACE CONTROL  FEEL AUGMENTATION SYSTEM           ABSTRACT OF THE DISCLOSURE      In a helicopter, a pilot-actuated lever controls, through linkage mechanisms, a servo valve to drive a hydraulic piston; the piston moves a swash plate which in turn controls movement of rotor blade pitch positioning mechanisms against the force of blade loading, caused by aerodynamic forces.  Blade loading, heretofore monitored visually by the pilot on a cruise guide indicator instru-ment, is used herein to control a secondary input to the servo valve, thereby to alter the position linkage mechanism which causes the force of a spring attached thereto to impose a force on the collective pitch control for blade loadings in excess of one-third of maximum allowable blade loads, in a direction tending to drive the control to lower collective pitch (lower blade loading).  This provides "feel" to the pilot in proportion to blade loading when at critical magnitudes.  A trim system is selectively actuatable to provide an input to the auxiliary valve which tends to maintain the collective pitch control in a selected position.

Title: Continuous production of alkyl acrylates free from  ether.
Inventor: ERPENBACH HEINZ
IPC: C07C67/08
Filed: 1976-11-19
Granted: 1980-08-12
Abstract: ABSTRACT OF THE DISCLOSURE:      Alkyl acrylates free from ether are made continuously by reacting acrylic acid with a C1-C4-alkanol, in a molar ratio of 1:1 to 1:2, in liquid phase, at 80 to 130°C, under 100 to 760 mm Hg, in the presence of an acid catalyst. More specifically, a reaction mixture of acrylic acid, alkanol and a sulfuric acid or organic sulfonic acid catalyst is continuously introduced into a reaction zone, the reaction mixture containing sulfuric acid in a concentration of 0.1 to 3 weight %, or the organic sulfonic acid in a concentration of 1 to 8 weight %. Reacting the reaction mixture over a period of 4 to 10 hours in the reaction zone. An azeotropic mixture of alkyl acrylate, reaction water and unreacted alkanol is distilled off near the head of a first distilling zone mounted on the reaction zone. The mixture is condensed and separated into an aqueous phase and organic phase. A portion of the organic phase and, in the event of the alkanol used being a C3 or C4-alkanol, also a portion of the aqueous phase are recycled to the head of the first distilling column, and remaining aqueous phase is removed. The balance portion of the organic phase is delivered to a second distilling zone, an azeotropic mixture of alkanol and ester, is distilled off overhead, condensed and recycled to the reaction zone, and ether-free alkyl acrylate is removed from the base portion of the second distilling zone. A portion of reaction mixture is continuously taken from the reaction zone, distillatively freed from high-boiling matter, the resulting distillate is admixed with a quantity of catalyst equivalent to that removed together with said high-boiling matter, and then recycled to the reaction zone.

Abstract: ABSTRACT OF THE DISCLOSURE      A protective relay circuit.  An electrical system signal quantity is monitored and applied to a filter and to a bipolar threshold device in parallel with the filter.  The bipolar threshold device has a zero output signal level as long as the magnitude of the monitored signal is less than some predetermined value.  When the monitored signal exceeds the predetermined value, the output of the bipolar threshold device will be substantially equal to the monitored signal level minus the predetermined value.  The output of the filter and the output of the bipolar threshold device are combined in a summing amplifier to provide a signal for controlling the trip coil of a circuit breaker.  When the circuit is use in an overcurrent or overvoltage protective relay, the combined signal is rectified and applied to a level detector which provides the signal for controlling the trip coil of the circuit breaker.  When the circuit is used in a distance or directional relay, the phase of the combined signal as compared to the phase of a second monitored signal determines the generation of the signal for controlling the trip coil of the circuit breaker.
